Hello. My name is ***** ***** I will be helping you today.I see that you have replaced a lot of stuff.. was any of it because it was bad? Is the battery dead when it wont try to start?
Customer: replied 5 months ago.
Alternator diodes were bad and battery crank A were low according to dealers and AutoZone the battery would jump immediately, it appears dealers just due the basic tests then replace these parts bcause they really don't spend their own time and money doing diagnostics, electrical checks etc..... Time is money.

So this is an ongoing problem? And you come out to start it in the morning and the battery will be dead dbut it will fire up with a jump or new battery?
Customer: replied 5 months ago.
Typically can be jumped in seconds, but it will be fine for weeks then won't start.... Doesn't matter if morning noon or nite, winter, spring, summer and fall..... Totally unexpected when it fails, usually about the time Inthink it is fixed then it lets me down again.
